我該如何解決這個錯誤？
sudo apt-get update
sudo apt-get install ruby1.8-dev
sudo apt-get install mysql-server
sudo apt-get install libgemplugin-ruby
目前我收到此錯誤：
sudo apt-get install ruby1.8-dev
Reading package lists... Done
Building dependency tree
Reading state information... Done
Package ruby1.8-dev is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or is only available from another source
E: Package 'ruby1.8-dev' has no installation candidate
答案1
您不必對 resources.list 執行任何操作
首先，apt-cache search ruby1.8
它會列出所有包。記下要安裝的所需軟體包的名稱，然後使用該軟體包名稱執行 sudo install 。
